I've been in a office where each workstation(Windows XP) have configured two static IP Address on the same NIC one for net : 192.168.3.0 and another for accessing net : 192.168.200.0 .
Since the IP address for net 192.168.200.0 is given only for accessing an Asterisk VoIP Server that has ip address : 192.168.200.125.
After seeing this type of configuration, i have some doubt ... it's not better adding a server with multiple ip address configured and then set a static route on the default gateway of the main network ?
Can achieve better performance with multiple IP Address or with a static route on default gateway?
When multiple IP Address on single NIC is a better choice ?
